This paper describes a user simulator based on analysis of VoiceXML description. A user simulator is a method to evaluate a spoken dialog system without the use of human evaluators. The new feature of our simulator is that it uses a VoiceXML description that describes the dialog system’s behavior. By using the VoiceXML description, the proposed simulator can be used for any dialog system that works with VoiceXML. We constructed a prototype of the user simulator and carried out an evaluation experiment. The experimental result showed that the dialog between the simulator and the dialog system had similar properties to that between human subjects and the dialog system.
